“Now Mick has to formally accept Lucas is his. You can tell by looking at the baby anyway.” A FRIEND OF LUCIANA GIMENEZ MORAD

Mick Jagger’s Brazilian bombshell girlfriend has got satisfaction from DNA tests proving the Rolling Stone rocker is the father of her baby boy, it was reported today.

The high-tech tests, conducted in London, showed that Luciana Gimenez Morad’s bundle of joy – whom she named Lucas Morad Jagger – is the star’s offspring, the London Sun reports.

The infant was born May 18 in New York – but Jagger denied he was the dad, setting the stage for the DNA testing.

It was the 29-year-old Morad’s claims that drove the final wedge between Jagger and his wife, Jerry Hall, who signed a $15 million divorce settlement earlier this month.

Jagger, who has six other kids, including four with Hall, is expected to agree to bankroll Lucas’ upbringing, The Sun reports.

The paper says the rocker’s lawyers gave him the news yesterday, on his 56th birthday.

Jagger’s publicist did not return calls yesterday. Morad’s lawyer, Raoul Felder, could not be reached for comment.

“She’s known it’s Mick’s all along and is just pleased she’s been fully vindicated,” a friend of Morad told The Sun. “She’s a bit annoyed she had to go through all the hassle of DNA tests, because it makes her look like a real tramp.

“Now Mick has to formally accept Lucas is his. You can tell by looking at the baby anyway.”

Morad met Jagger at a Stones concert in Rio de Janeiro last year.

Hall and Jagger had been together for more than two decades, during which the rocker had countless affairs.

But the two avoided a messy court fight and agreed to a divorce deal that kept them on good terms.
